Overview

EN 14066:2013 is a European Standard developed by the European Committee for Standardization (CEN) that specifies a precise test method to evaluate the resistance of natural stone to ageing caused by thermal shock. Thermal shock refers to the deterioration or changes that occur in natural stones due to sudden temperature variations, which are common in many environmental and industrial conditions. This standard sets out a comprehensive procedure to assess how natural stones withstand these rapid temperature changes, ensuring their durability and suitability for various applications.

Key Topics

• Thermal Shock Test Method
  The standard details a cycle which involves heating natural stone specimens to 70 ± 5 °C for approximately 18 hours, immediately followed by immersion in water at 20 ± 5 °C for 6 hours. This cycle simulates the effects of sudden temperature changes and is repeated typically 20 times.

• Specimen Preparation and Dimensions
  Specimens must be sampled from a homogeneous batch with specific dimensional criteria relative to the stone grain size. Thickness ranges between 25 mm and 100 mm, with proportional length and width as defined by the standard to ensure consistent and relevant test results.

• Performance Evaluation Parameters
  The standard requires measurement of:

  • Visual changes such as cracking, scaling, and exfoliation.
  • Flexural strength differences before and after thermal shock cycles (measured according to EN 12372).
  • Non-destructive testing including dynamic elastic modulus (EN 14146), ultrasound pulse velocity (EN 14579), and open porosity (EN 1936).

• Data Analysis
  Changes in stone properties are calculated as percentages to quantify deterioration:

  • Flexural strength change (∆F)
  • Dynamic modulus of elasticity change (∆E)
  • Ultrasound pulse velocity change (∆v)
  • Open porosity change (∆ρ)

• Reporting Requirements
  Detailed test reports must include specimen identification, testing conditions, observed alterations, measured property changes, and any deviations from the standard procedure.

Applications

EN 14066:2013 is crucial for industries and professionals involved in:

• Construction and Architecture
  Ensuring that natural stone materials selected for facades, flooring, cladding, and monuments demonstrate adequate resistance to environmental thermal stresses, thereby extending their service life and appearance.

• Quality Control and Product Certification
  Laboratories and manufacturers use this standard to assess natural stone batches for performance certification, aiding in compliance with client specifications and regulatory requirements.

• Research and Development
  Enables material scientists to study the effects of thermal ageing on stone durability, assisting in the development of treatment processes or enhanced stone products with improved resistance to thermal shock.

• Maintenance and Conservation
  Provides guidelines for evaluating historic stone materials before restoration or preservation initiatives, determining necessary protective measures.

Related Standards

EN 14066:2013 complements a suite of test methods for natural stones that address various durability and mechanical properties, including:

• EN 1936 – Determination of real density, apparent density, and total/open porosity
• EN 12372 – Flexural strength under concentrated load
• EN 14146 – Dynamic modulus of elasticity by resonance frequency
• EN 14579 – Sound speed propagation measurement
• EN 14147 – Resistance to ageing by salt mist
• EN 12371 – Frost resistance
• EN 12407 – Petrographic examination of natural stone

These interconnected standards offer a holistic approach to natural stone testing, enabling stakeholders to comprehensively assess material quality and suitability for diverse environmental conditions.

Implementing EN 14066:2013 ensures robust evaluation of natural stone resistance to thermal shock ageing, supporting the selection of durable materials for sustainable construction and preservation. This standard plays a vital role in quality assurance and material performance optimization within the natural stone industry.
